Drunk Driving or Drinking and Driving is the act of operating a motor vehicle after having consumed alcohol (ethanol) or other drugs, to the degree that mental and motor skills are impaired. Driving under the influence drunk driving or drink-driving is the act of operating a motor vehicle (and sometimes a bicycle or similar human-powered vehicle) after having consumed alcohol (ethanol) or other drugs to the degree that mental and motor skills are impaired. The permissible legal blood alcohol limit varies from.05 to .10 depending upon the state. Moreover in some states you do not even have to be operating a motor vehicle to be charged with DUI – you only need to be sitting behind the wheel; for instance if you’ve pulled over to sleep it off you can still be charged with DUI in certain states.

Each state’s Department of Motor Vehicles maintains a database of motorists including their convicted traffic violations. The conviction for alcohol-impaired driving is generally followed by License suspension or revocation. As per administrative license suspension procedure licenses are taken before conviction when a driver fails or refuses to take a chemical test. Forty-one states and the District of Columbia have administrative license suspension laws. Different terms are being used for the purpose depending upon your state. Some of the popular terms used are:

• DWI: Driving While Intoxicated
• OUI: Operating under the Influence
• OWI: Operating While Intoxicated
• OMVI: Operating a motor vehicle while intoxicated
